T0 ALL WHOM ITVMAY CONCERN i Be it known 'that I, E. A. DE CAMP, of the city and .county of St. Louis, and State of Missouri, have invented a. VneWnnd use ful. Improvement in Stoves; and do hereby declare that the following is a full and clear description thereoi','refe reuce being had to the accompanying drawings, and to the letters oi' reference marked thereon. Y

This invention consists in an improvement upon' the-common egg-shaped coal-burning stoves, the said improvement being the addition to the said stove of an annular cooking-top, thus adapting the best-known softcoal-burning stoveto -culinary'purposes.`, i

'.lo enable those skilled in the art to make and use my improved stove, I will .proceedpto describe `its conf struction and operation. l i

Figure 1 of the drawings is an elevation of the improved stove. Figure 2 is a top plan of it. l I Figure 3 is a central sectionalelevation.v Figure 4 is a'bottoln plan ofthe heat-distributing disk. v The base of thestove, A, may be' the common egg-shaped sto've, used for heatingipurposes only up to the present time, and found to 4be the b estadapted to the use ofLbituminous coals. The top of this'part of the stove is covered with a convex diaphragm, B, perforated with openings b, for the escape-of the: smoke antibot gases into the annular chamber C, formed between the annu-lar disks C1 and C2. The lower one ofthese disks,4

vC1, should be inclined upward from its centre to the periphery, so as to contract thesection of the chanrber at its periphery in such a manner as to leave no deadA atmosphere in the a'ngl'e formed Vby the connection ofthe .disk C with a vertical wall. The disk C2," whichforms the top 'plate of the stove, should have a horizontal ilat v top surface, and be perforated with openings, c, for the recept-ionofl cooking-vessels. A central opening, c1, is for the smoke-pipe Each of the opcnings'c is provided with a covering-plate, e2, secured by means of a chain,

e3,V With-the pipe- P, and a hook, p, is attached to the said pipe at the cud of ea'ch chain, for-,the purpose of hang;A

ing up the said covers out of therway when not in use. This device of chains and hooks is of peculiar utility,

as this stove is `especially designed and adapted for` use as a deck-stove ou emigrant and other, vessels. A

radiating diaphragm, O, convex on its `lower surface, and inclined upnvardfrom its centre to its periphery, is interposed between the disks Cl and C2, as clearly shown in figs. 3 and 4. The periphery of this diaphragm Where itjoins the disk C2 falls in a circular line, bisecting the openings c, or nearly so,thercfore semicircular notches, c, are cut in it, so as to fully uncover the bottoms of the openiugsc, as is represented in i-g. 4. The

openings b, in the diaphragm B, are placed directly under the salient wingso5 ofthe diaphragm C3 between the openings c, as is also clearly shown in fig. 4. v i `This' arrangement compels the smokeand hot gases arisinglfrom theburuing fuel in A to pass directly' under each ofthe cooking-places c, and in-so contracted aspaceas to utilize the-greatestpossible amount of caloric. The semicircular notches c* cnt in the periphery of diaphragm G3 afford openings between C2 and O3 i'or the passage ofthe smoke intothe smoke-chamber C4, shown in fig. 4, andfrom thence it passes up -into the'pipe l?. The tortuous passage presented for the exit .ofthe smoke through the chambers C andy C4, and the iuterposition of the diaphragms B and C3, which Whiiein ,fuse become heated, render this arrangement of stove nearly a suroke-consumer, and a great saving of fuel isV thereby eliected.

Having described niy invention, what ,l claim, is-J 1. Theannular cooking-top Cf C2, in combination with the stove A, substantially as described and set forth. I claimthe diaphragms B and C3, when combined with the disks C1 and C2, substantially as dcscribed and Set-forth. I 4 E. A. CAMP.
